It has got a storyline version aswel but the same as COD its mainly about the online gameplay. The best way to describe it is COD is for daft wee boys who want to mess about and battlefield 3 is more for people who are interested in proper gameplay and tactics etc its more team based rather than one person running around like Rambo it takes a while to get into it but when you do you'll realy enjoy it! Battlefield 4 is due out towards the end of the year
